O/W fat gel as well as preparation method and 3D printing application thereof

The invention discloses O/W fat gel as well as a preparation method and 3D printing application thereof, and belongs to the technical field of low-fat fat green manufacturing and fat 3D printing. According to the preparation method based on the protein-polysaccharide-grease O/W fat gel, protein microgel particles, macromolecular water-soluble polysaccharide, solid fat and liquid vegetable oil are used as raw materials, a mixture of the protein microgel particles and the polysaccharide is used as a water phase, and a mixture of the solid fat and the liquid vegetable oil is used as an oil phase; the water phase and the oil phase are mixed and emulsified; the formed O/W fat gel has good plasticity and pattern mounting characteristics, and also has good application potential in food 3D printing application. 本发明公开了一种O/W类脂肪凝胶及其制备方法和3D打印应用，属于低脂类脂肪绿色制造和脂肪3D打印技术领域。本发明基于蛋白质-多糖-油脂O/W类脂肪凝胶的制备方法，所述方法是以蛋白质微凝胶颗粒、大分子水溶性多糖、固体脂肪、液态植物油为原料，采用蛋白质微凝胶颗粒和多糖的混合物作为水相，固体脂肪与液态植物油混合作为油相，将水相和油相混合乳化而成；形成的该O/W类脂肪凝胶具有良好的可塑性和裱花特性，在食品3D打印应用中表现
